"This'invention relates to devices for cutting paper patterns to the designed shape for the garment trade, and its object is to pro;- videa noveldevice of this kind which operates efficiently.

A furtherrobject ofthe invention is to provide an apparatus for the purpose out lined which is exceedingly simple in' construction and thereforeinexpensiveto manufacture.

Another object of'the invention to to provide a device of the character contemplated which may be operated with a minimum amount of skill andwith safety.

With these objectsin view, and any others which may suggest themselves in the description and claims to follow, a better understanding of the inventionmay be had by reference to the accompanying drawing, in which I c Figure 1 is an elevation of the device as viewed from the rear or remote side;

Figure 2 is an enlarged section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a plan view of a regulating de- V10 5' v v Referring specifically to the drawing, 5 denotes a long wood board which is designed to form the base of the device. The latterv is of a portable nature and is therefore capable of beingmounted on any work table and fastened down or not, as desired.

Upon the base 5 1s mounted a long metal support 6 having standards? and 8 at its ends. Between the'standards are disposed two long shafts 9 and 10, these being verticall spaced and At one end the sha ard 7 and inside of the latter the shafts carry meshing gears 9 and lO whereby the shafts are geared for motion in opposite directions. The shaft 9 extendsthrough the standard to receive a large gear'll which in meshing with a pinion 12 carried by an electric motor 13 mounted on the, base 5, provides reduced speed for the shafts.

The driving mechanism described above is grouped at one end of the base; and the operating or cutting mechanism is also grouped, at the opposite end of the base, whereby to leave the space between the shafts 9 and 10 unobstructed for a long distance, for a reason soon to become evident.

The standard 8 is supplemented in an upward direction by a transverse plate 14, which has a horizontal top bend 14 and s 9 and 10 are journaled in the stand-v formsywith the-standardi', a support for a long bracing strip 15, "suitable securing devices 16be1ng applied to hold the strip. in place. i A terminal downbend -15 of the stripaforms a bearing for the corresponding end of the shaft 9,""while the forms a like bearing for the shaft 10.-

' Inlinewi'th the-plate 1d, the shafts carry staggered circular cutters 9 and 10 ,'respec tively,"of thebeveltype, and these overlap with theirflc ontiguous surfaces midwaybe tween'theshaftaas indicated in Figure 2. A work supportor table 17 is disposed at the working level of'the cutters 9 and 10 a slot- 181 being cut in thetable to clear the cutters and that part-of the plate 14 adja standard 8 centtheretol The tableyis substantially. rectangular, and is rounded to form vertical or sloping sides 17 n which fit the sides and the end of the base 5 and are suitably attached thereto. p

In operating the device, the current is turned on by means of a suitable switch, whereby to cause thecutters to turn in the directions denoted by arrowsin Figure "2. The pattern sheet is then rested on the table 17 andfed through the cutters from the left toward the right, according to Figure 2. It will be noted that the front edge of the plate 1 1 is fashioned to follow the form of the cutters,whereby t'o provide a narrow guard is at the issue-point of the cut. This guard separates the divided sections of the pattern sheet, so that they will not again move into the path of the cutters and become damaged. The guard is made narrow in order to allow lateral freedom to the cut sections as the pattern sheet is swung to one side or the other along the path of the design. In this con nection, it will be seen that the 'long horizontalfspace between the shafts9 and 10 is provided to accommodate the pattern sheet and permit the. same to swing freely irrespective of size.

In order that the pattern may not bulge as fed to the cutters, or feed irregularly, a regulating device is provided. As shown more clearly in Figures 2, and 3, this device mainly comprises two superposed rollers 18 and 19 between whichthe pattern sheet is passed before it is fed to the rollers. The roller 18 is journaled in the table, projecting slightly above the same through a slot 20: and the roller 19 is supported atits ends by two bracket arms 21 whose opposite ends are carried by a spindle 22. The latter is high to perm-it ing strip 15.
